To all whom tmay concern: f

Be it known that I, I-IAL MULLEN, a citi-` zen of the United States, and a resident `of the city of New Decatur, in the county of `Moi-gan, State of Alabama, have invented certain new and useful Improvements in Endv Sections for Radiators, of which the following is a specification.

rlhis invention relatesbroadly to radiators and more especially to an end section for a radiator. i

Thev principal obj ect of the present invention is to provide anend section adapted to coperate withfthe ordinary commercial type ofintermediate sections and whereby the end section is so partitioned as' to cause the heating fluid tobe distributed throughout the radiator from the top portion thereof.l

A further objectl of the present invention is the provisionof an end section adapted for cooperation with commercial intermediate sectionsy whereby'wthe radiator may be piped for returniiowatthe same end as the inlet, or the radiator may kloetapped for a flow wherein the inlet isat one end of the radiator andthe outlet is at the other end thereof.

Still more1k specifically the object of the present invention is to provide a construction wherein the end section of the radiator is partitioned in ysuchmanner as to present independent vertical columns, one column of which is tappedfor the inlet and the other column of which is tapped for the outlet.

Still other and further objects of the present invention will in part be obvious and will in part be pointed out hereinafter in the specication vfollowing by 'reference to the accompanying drawings forming a part of the said specification, andwherein throughout the several figures of the drawings like characters are used to represent like parts. .f f

Fig. 3 is a sectional view takenv on lines B-B Fig. 2. Fig. i is a perspective view illustrating the circulatory systemlwhere the inlet is at Vone end and the outlet is at the other. end of the radiator.

END SECTION FOR RADIATORS.

end sections, is a hollow member having a .continuous or unbroken passage except for intermediate walls provided to increase the radiating surface. In suoli constructions where the sections are connected to provide a continuous opening through the upper portion, there is no positive flow of the iiuid through the upper connections. The sections in this form of radiator are filled with a heating iiuid and circulation in the radiator, if any, is due to thermal conditions. Furthermore, in radiators of the character specified it is'necessai'y to provide an iniiow at one end and an outflow at the other'end.

The device comprising the construction of the presentinvention, which will be more clearly described hereinafter, comprises an i end section adaptable to conform to the cointhat it comprises two independent vertical i columns or legs, both of which lead to a connector opening at the top and one of which columns is provided with an inlet opening at the bottom, the other of the said columlps Y this construction it will be noted'that the fluid is at least compelled to Atravel tothe top of the end section, and since therrst out let opening is provided at this point the iiuid is given the first opportunity to distribute itself from the top of the radiator.

Referring now to the drawings and more particularly to Figs. 1, 2 and 3, the end section X comprises body walls 1 which terminate at the lower end with integral feety or legs 2. In the form ill-ustrated in Figs. 1, 2 and 3 draft openingse are provided, as is common in the art, to facilitate radiation. Intermediate the body` walls front and back is provided a lower partition 5 and inter` mediate one pair of draft openings is provided an upper partition 6. It will be noted that the partitions 5 and 6 divide the end section X into vertical columns Y and Z. The upper end of the vertical columns, and in the common zone thereof, is provided on the back of the end section X a connector opening 7 which is adapted to cooperate with the connector opening in the ordinary radiatorsection l/V. The bottom of the vertical column Y is preferably provided with one inlet opening 8 which is located on the front yside of the end section X. The vertical column Z is provided at its lower end with three openings 9, 10, and 11, any one;A`

or all of Which may perform the function of outlet openings. The opening l0 it istoA be noted is at the back Oftheend section and the openings 9 and 11 are ai;` thejront thereof. l,

Referring to the igs. l, 2 and 3 it Will be,Vv noted Vthat the inlet opening 8 is'indicated' as being provided with asupplyy pipefl that may be provided with a suitable valve 14.; Itis' alsotobe noted that the opening 11:.- is f provi-dedv with an. outletl ori return pipe l5@ In these figures of the. drawings; re-y ferred ito the-` circulation ofthe. heating fluid is' vindicatedbythe arrows 'Gn It will:v be notedy that the 'fluid upon enteringthe column Y; through th'esupply'k pipe 12 lmaires ai vertical ."direction tolithe 1 connector 'open-f finglt :fromwhioh opening the intermediate It' Wilflfbernoted thatfth'e Figs; :1, 2 fand' 3' illustrate; a.. construction wherein the end sectioniis. u-tilized for, pip-ing@ wherein bothl the i inlet'.l and outlet are. tapped into, onerend sectionpfthe radiator andz'avherethis is desira'ble. ther-outlet 'openingQ is preferably stopped by' a`r screwiplug 16.* This opening 9;'.is alinedvwithficonnector opening 10, and
